FLASHING FOR METAL ROOFING.

SPECIFICATION forming part of Letters Patent No. 364,304, dated June '7, 1887.

Application filed April 7, 1887. Serial No. 233,977. (No model To all whom it may concern.-

Be it known that I, LoNeLnY LEwIs SAGEN- DORPI-I, a resident of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Flashings for Metal Roofs, of which the following is a specification.

The features of my invention and the advantages arising from their use will be apparcut from the following description.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective View of part of the top of a house, illustrating various steps in the application of i my improved flashing. Fig. 2 shows a piece of the textile fabric employed cut for application to an angle. Fig. 3 represents my im- 7 proved flashing applied to a re-entrant angle. Fig. 4 illustrates the mode of preparing the flashing for use.

The flashing H consists of a backing of some textile fabric, A, such as cheese cloth, on which is spread a thick coating of cement or glue, B, which is insoluble in water, and thus renders the flashing water-proof.

\Vhere the metal roof comes in contact with the fire-walls it is provided with a flange, G, which is turned up against the wall and fitted as snugly against it as possible, being held in position by nails D. A priming composition is then applied to the wall and to the flange and edge of the metal roof. This priming composition has the property of adhering strongly to wood, brick, or iron. The cement Bis preferably of the same composition, but

of greater consistency. A strip of flashing, H, prepared as described, is now applied so as to cover the nail-heads and the joint between the flange O and the wall. The priming composi- 0 tion causes the strip to adhere tightly to both the roof and the wall, and its flexible character enables it to be accurately fitted in place. The priming composition is again applied.

Theflashiug is preferably covered with a coat of paint, like the remainder of the roof. 5

In making joints about chimneys the angles are preferably first protected by a piece of flashing, F, cut as shown in Fig. 2, and applied as shown at E, Fig. 1. The regular strip of flashing is carried around the chim- 5o ney in the usual way and closes over this piece. For reentrant angles the picceF is applied as indicated in Fig. 3. This material for flashing may also be advantageously employed in repairing leaks in the roof by simply 5 pasting it over the leaky joint, as indicated at G in Fig. 1. The readiness with which this flexible flashing may be applied renders it particularly useful; but the absolutely tight joint which it forms is its chief advantage. 6o

Vhat I claim as new and of my invention, and desire to secure by Letters Patent, is-

1. A flexible water-proof flashing,in combination with a metal roof, substantially as set forth.

2. A flashing for corners, consisting of a short strip of flexible water-proof material partly split through the center, substantially as and for the purposes set forth.

8. The combination of a wall and a metal roof having a flange turned up against the wall, and flexible water-proof flashing, and substance for causing the flashing to adhere to the roof or wall, substantially as described.

4. The combination of a wall and a metal roof having a flange turned up against the wall, and flexible water-proof flashing, the water-proof material being applied to the outer side, the flashing being secured to roof and wall by adhesive substance, substantially as set forth.
